Securities at Old Trafford ejected a Manchester United fan for alleged racial abuse aimed at Liverpool defender Trent Alexander-Arnold.
SunSport can reveal that the security teams stepped in after a supporter allegedly shouted “you f***ing black c**t” at the right back on Sunday.
The incident happened during the first half close to the players’ executive boxes in the Stretford End and caused fury among supporters who witnessed the incident.
They immediately called for stewards to throw out the fan and agreed to co-operate with anybody looking into the incident.
United maintained that a range of options, including indefinite bans and police involvement, are available to them.
A United spokesman said: “We are aware of an incident at yesterday’s game where an individual in the home section has allegedly engaged in racial abuse.
“The individual was identified and ejected from the stadium.
“We are currently investigating the matter as a priority.
“Racism and all forms of discrimination are completely unacceptable and do not reflect the values of our club.”
In a separate incident, Alex Oxlade-Chamberlain was told to “f*** off” by United fans as he had a fist bump offer rejected by a supporter.
